Many people will not only ask such a sentence after understanding the 7075 aluminum plate, that is, why should the 7075 aluminum plate be numbered 7075? That is to say, why the 7075 aluminum plate is in the 7XXX series. In fact, these are closely related to the components contained in the 7075 alloy aluminum plate.
What many people are curious about is what the 7075 is. In fact, this 7075 is only a national code name for alloy aluminum plate products, and the number of these is specifically the content of elements in the alloy aluminum plate.
It is known that the zinc element in the 7XXX series is the main alloying element. When manufacturing the 7075 alloy aluminum plate, magnesium is added to the zinc element of 3 to 7.5 percent, which means that the formation is significant. Strengthening effect of magnesium zinc. Thus, the heat treatment effect of the alloy aluminum plate is far better than the heat treatment effect of the binary alloy aluminum plate with pure aluminum and zinc elements. Increased the content of zinc and magnesium in the alloy aluminum plate, while improving the heat treatment effect
The national standard code, specifically the tensile strength of the element content, will be further improved, but it should be noted that the resistance of the alloy aluminum plate to stress corrosion and flaking corrosion will decrease, which is the so-called must-have Lost. However, after the heat treatment, the alloy aluminum plate can achieve extremely high strength characteristics, so it can be said that this trade-off is quite worthwhile. In the 7075 material, some copper and chromium elements are generally added, so that alloys such as 7075-T651 can be synthesized. These top products are also the best products of alloy aluminum plates.
Because this 7075 alloy aluminum plate has many excellent quality and plasticity, it is often used in various aerospace businesses, mold processing industries, machinery and equipment industries.
